' WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 758,626, dated May 33,1904.

Application filed August 11, 1903.

To all whom it may concern:

Be it known that we, EDWIN DOUDEN and AARON B. RoBB, citizens of theUnited States, residing at Brooklyn, in the county of Kings and State ofNew York, have invented a new and useful Weather-Strip, of which thefollowing is a specification.

This invention relates to weather-strips, and more especially toweather-strips for use upon window-sashes between the sash and theadjacent surface of the window-frame.

The object of the invention is to provide'a weather-strip of the classdescribed which is I adapted to be automatically thrown out of contactwith the surface of the window-frame when it is desired to raise thesash and which is automatically brought into operative engagement withthe surface of the frame when the sash is lowered.

A further object of the invention is to pro' vide, in weather-strips ofthe class described, an improved form of operating means whereby theweather strip can be adjusted to correspond to any shrinkage of thewindow-frame away from the sash, or vice versa, and also to provide anoperating mechanism which shall at all times be reliable and positive inits action.

With the objects above mentioned and others in view, as will appear asthe invention is more fully disclosed, the same consists in theconstruction and combination of parts of a weather strip hereinaftershown and described and having the novel features thereof fully pointedout in the appended claims.

In describing the invention reference will be had to the accompanyingdrawings, in which corresponding parts are designated by the samecharacters of reference in the several views, it being understood thatvarious changes in the form, proportions, and exact mode of arrangementof the elements may be resorted to without departing from the spirit ofthe invention.

In the drawings, Figure 1 is a view in side elevation of a sash-stilewith the weather-strip mounted thereon. Fig. 2 is a reverse plan view ofthe upper strip-supporting plate. Fig. 3 is a sectional view on the line3 3 of Fig. 1 looking downward. Fig. 4 is a plangerial No. 169,100. (Nomodel.)

. view of the lower strip-supporting plate and V the parts associatedtherewith. Fig. 5,-is a detail perspective view of a portion of thewindow-frame and the cam-plate mounted thereon. Referring to thedrawings by reference characters, '15 designates one of the verticaljambs of a window-frame, and S designates the window-sill.

The numeral 1 designates one of the sashstiles, which is grooved uponits outer face, as shown, to form a seat for the weather-strip. In thegroove, which is designated 2, there is pivotally mounted theweather-strip 3, which consists, preferably, of a strip 4., of rubber ofsuitable thickness, and a pair of plates 5, presenting flat innersurfaces and rounded outer surfaces, as best seen in'Fig. 2. The plates5 are somewhat narrower than the strip of rubber, and the strip ofrubber is riveted between them, as shown in Fig. 2, leaving the edges ofthe rubber projecting beyond the edges of the plates 5 at either sidethereof. The strip 3 is supported in sockets 6, eccentrically mountedupon pivots fitted in openings in plates 7 and 8. The plate 7 which issecured at the upper end of the sash-stile 1, is notched at 9 for thepassage of the sash-cord l0 and is secured in position by means ofscrews or other suitable fastening means. The plate 8 is attached to thebottom of the sash and is provided at its outer end with a notch for thepassage of a rib 11 on a striking-plate 12, which is secured to thewindow-frame jamb F at its juncture with the sill S. The plate 12 issupported at its upper end on a screw 18, engaging the jamb of thewindow-frame, and .the lower end has a transversely-arranged slot 1 1,through which passes a screw 15, by rwhich the plate is secured indifferent positions.

Associated with the socket 6, which turns upon the plate 8, is an arm16, which is normally held by means of a spring 17 at right angles tothe plate 8 and disposed directly across the opening or notch 18 in theend thereof. The spring 17 is a light leaf-spring and has one end fixedupon the plate 8, while the other is free to engage with a shoulder onthe arm 16 to hold it normally extended across the notch in-the plate.-The arm 16 is so placed in relation to the strip of rubber forming thecentral part of the pivoted weatherstrip that when the arm 16 isdisposed in the position shown in Fig. 4, with one end directed acrossthe notch 18, the weather-strip will be turned so as to lie within thegroove 2, formed in the vertical stile of the sash. The arm 16 is held,whenever the window is raised, in the position already described; butwhen the window is lowered the arm 16 engages with the rib on thestriker-plate, and that rib, being formed with a slope inward anddownward, forces the arm 16 around with the socket 6 attached theretountil the edge of the weatherstrip has been brought into contact withthe jamb of the window-frame, so as to be effective in excluding airfrom the room. If on account of the shrinkage of the window-sash or theseparation of the timbers forming the windowframe the sashes hang loosewithin the frame and allow air to pass around the edges thereof in spiteof the action of the arm 16 and rib 11, the effect of the arm upon thestrip may be increased by loosening the bolt at the bottom of thestriker-plate and shifting it slightly outward toward the arm 16, sothat a greater amount of pivotal movement of the arm and theweather-strip will result from the engagement of the arm 16 with the ribon the striker -plate, When the window is raised and the arm 16 is helddirectly across the notch 18 by the action of the spring engaging saidarm, the rubber edge of the weather-strip will be out of contact withthe window-frame and the sash will be susceptible of freer movement,while the rubber is completely protected from wear.

While rubber is the preferred material of which to construct the centralor body portion of the weather-strip, rubber may be dispensed withandcheaper materialsuch as leather, heavy felt, or even cloth suitablyfolded-may be substituted in lieu thereof.

Having thus described the construction and use of our invention, what weclaim as new, and desire to secure by Letters Patent, is

1. The combination with a window-sash having a groove in the outersurface of one of its sides, of a weather-strip pivotally mounted insaid groove and held normally out of contact with the window-frame, andmeans operative on the descent of the sash to swing the strip intocontact with the window-frame.

2. The combination in a device of the class described, of a sash havinga groove on the outer surface of a side member thereof, a weather-strippivotally mounted within the groove and normally held in a plane at anangle to the plane of the sash, and means, operated by lowering thesash, to swing the weather-strip into operative position.

3. The combination in a device of the class described, of a window-sashhaving a groove extending longitudinally of one side member thereof onthe outer face, a weather-strip pivotally mounted in said groove, acam-surface provided on the window-frame at the bottom thereof, and anarm mounted on the weatherstrip and adapted to engage with said cam.

4. The combination with a window-sash, of a weather-strip pivotallymounted at one side of the sash, means for normally holding saidweather-strip out of contact with the windowframe, an actuating-armprojecting from the weather-strip, and a cam adjustably mounted on thewindow-frame in position to be engaged by said arm.

5. The combination in a device of the class described, of a window-sashhaving a longitudinally-disposed groove on one of its side members, apivotally-mounted strip in said groove and having an arm projectingtherefrom, a spring engaging said arm to keep said weather-stripnormally in inoperative position, and means on the window-frame toengage said arm as the window is lowered to operate the weather-strip.

6. The combination in a device ofthc class described, of a window-sashhaving a longitudinally-disposed groove on the outer face of one of itsside members, supporting-plates at the ends of said groove, socketseccentrically mounted on pivot-pins inserted in said supporting-plates,a weather-strip fitted into said sockets, and means, operated byloweringthe sash, to swing the weather-strip into operative position.

7. The combination in a device of the class described, of a window-sashhaving a longitudinally-disposed groove on the outer face of one of itsside members, a weather-strip consisting of a strip of yielding materialand a pair of plates between which said strip of yielding material issecured, said weatherstrip being pivotally mounted in said groove andnormally held in inoperative position, and means, operated by loweringthe sash, to throw said strip into operative position.

8. The combination in a device of the class described, of a window-sashhaving a longitudinally-disposed groove on the outer face of one of itsside members, an eccentrically-pivoted weather-strip within said groove,an arm projecting from said strip in the same vertical plane therewith,a spring engaging said arm to hold the weather-strip normally ininoperative position, and a striker-plate adjustably mounted on thewindow-frame and provided witha rib presentingadownwardly and inwardlyinclined cam-surface for engagement with the arm associated with theweatherstrip to throw the strip into operative position.

In testimony that we claim the foregoing as our own we have heretoafiixed our signatures in the presence of two witnesses.
